Mr D Food service sucks. Do not use them!

On Wednesday 23 Dec 2020 I ordered food via Mr D Food to the value of R1316.20 An hour after my order was supposed to have been delivered I contacted Mr D Food to enquire about my delivery. I then got an email to say that the delivery could not be completed as there was a problem. They claimed to have called me and that I did not answer my phone (which is not true as I do not have a record of any incoming or missed calls). I was then told that they messaged me on the “app”, which I do not have. The consultant, Saarah, confirmed that they would give me a full refund. This was after she told me that if I am going to keep being upset with her, she will end the call. (At this point I was extremely peeved, to say it nicely). On Tuesday 29 Dec 2020 (almost a week later) I again made contact with Mr D Food via email enquiring about my refund. I was eventually told that it was loaded on my Mr D Food wallet, which I will find on the “app”. I again explained that I do not have the “app” loaded but to no avail. I asked them to please explain where they loaded my refund since I did not have the “app”. I also asked them to call me because I have no idea how to find my refund. However, every single time I get the same response, "your credit has been loaded onto your wallet!" All my correspondence about my refund was done via email, except for the initial conversation with Saarah which was via a landline.

So, do they now expect me to continue calling them? Is this the kind of customer service that they offer? I have never and will never use MR D Food again!
